Lesson 8 Your adviser and agreement in principle
Module 2 | Learning aim: Understand who helps you and what preliminary approval means.
Mortgage advice for a regulated home mortgage must come from an appropriately authorised firm or an appointed representative operating under an authorised firm. Check the firm, permissions and any principal firm through the FCA service, using independently verified contact details. Ask which lenders and products the adviser considers; regulation does not mean every broker covers every deal. [S15,S22]
Know how your broker is paid
The broker must explain their fees, when you pay and any refund terms, and whether they receive lender or third-party commission. They must explain any offset against your fee. For relevant residential mortgages, the commission amount must be disclosed, or you must be told that it will appear later in the mortgage illustration if not yet known. Ask for these details in writing. [S21]
Receiving commission is normal; it does not remove the duty to act in your best interests. A broker must not steer you to a lender because it pays them more, at the expense of a suitable recommendation for you. Ask why the recommended deal fits your circumstances and how it compares with the alternatives within their stated range. [S22]
Look at the whole deal including incentives
Ask your broker to check suitable deals for free valuations, cashback and any expressly included survey benefit. Compare interest, product and broker fees, incentives and restrictions over the same period. A free extra does not automatically make a mortgage better value. For illustration, £25 more each month over two years costs £600, outweighing £500 cashback before other differences.
Check the cashback conditions and payment date. Some lenders pay it after completion; Nationwide currently states within one month, depending on the product. Do not rely on that money for fees or deposit funds needed beforehand. Offers change, so confirm the actual mortgage terms. [S24]
An agreement in principle is an initial indication of potential borrowing, subject to checks and conditions. It is not the final mortgage offer. The lender must also consider the property and the full application. Keep this distinction in mind when an agent asks whether your mortgage is arranged. [S7]
For a new build or buying scheme, ask whether the adviser has experience of that route. Explain how long you expect to stay, your comfortable monthly limit and any circumstances that could change. Ask them to compare an ordinary purchase with a scheme assisted purchase where both are available.
Keep their written explanations so you can return to them when tired or unsure. You can ask for a second conversation rather than trying to absorb every detail at once. Professional advice is most useful when the adviser understands your actual life as well as your income.
Powwow Tip
Ask for a clear explanation, not just a borrowing number.

Renting a room and specialist borrowing
Some lenders can consider expected lodger income as well as your main income, potentially increasing the mortgage available. Bath Building Society’s Rent a Room mortgage is one example. It is subject to lending criteria and approval, and lodger income cannot be the only income for that product. Ask a regulated residential mortgage adviser which lenders accept it, what evidence of achievable rent they require and how much they will count. Do not assume every lender will lend more. [S28]
Compare the benefit with the practical reality of sharing your home. Budget for extra bills, maintenance and periods when the room is empty or rent is unpaid. A larger mortgage remains your responsibility. Check whether you could manage the payment without a lodger and keep a reserve.
The Rent a Room tax scheme
As checked in October 2026, the government’s Rent a Room Scheme allows up to £7,500 per tax year in qualifying gross receipts from furnished accommodation in your only or main home to be tax-free. The threshold is £3,750 if someone else receives income from letting accommodation in the same home. This is not £7,500 for each room. [S29,S30]
The test uses receipts before expenses, including relevant payments for meals or services and contributions to bills. For example, £600 a month for 12 months totals £7,200; another £50 a month for bills would bring the total to £7,800. If receipts exceed your threshold, complete a tax return and check whether using the scheme or normal income-and-expense rules is more suitable. Keep records and ask a tax adviser when needed. [S30]
Permissions and responsibilities
Tax relief does not itself give permission to let a room. Confirm the lender’s terms, check your lease or tenancy where relevant and tell your insurer. Agree rent, bills, shared facilities and notice arrangements in writing. Check safety duties and any local licensing requirements with the council; in England, Right to Rent checks also apply to lodgers. Rules depend on where the property is and how the accommodation is shared. [S31,S32]
Networking groups and Property Powwow resources can help you find people to ask. A letting agent with relevant local experience may help you understand practical compliance, while the appropriate adviser deals with finance and a solicitor addresses the agreement. Check expertise and fees rather than assuming every introduction includes free advice or a compliance guarantee. See Lesson 21 for building your support network.
Guest houses and mixed use properties
If your longer-term plans include a small guest house or a property combining residential and business space, specialist commercial or semi-commercial finance may be available. Allica Bank, for example, lists guest houses and mixed-use property among commercial mortgage business types. Approval depends on the property, intended occupation, business evidence and lender criteria; it is not an ordinary first time buyer mortgage simply because you will live there. [S33]
A specialist commercial broker you meet through networking or Property Powwow may help you explore suitable routes. Explain exactly how you will use the property. Compare deposit, fees, repayment terms and evidence required, and ask whether the proposed finance is regulated and what protections apply. Check planning, permissions, insurance and possible business rates with the relevant professionals. [S34]
Exploring and learning can reveal a possibility you had not considered, which may suit your longer-term goals. Research the responsibilities as carefully as the opportunity before choosing it.
Your next step
If room letting interests you, ask your adviser about acceptable income evidence and permission, then run your budget with no lodger income. For a business property, write down its intended uses before approaching a specialist broker.
